Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE 4 Claims.

My present invention relates to adjustable window screens, andparticularly to improvements over my former U. S. Patent No. 1,957,339of May 1, 1934, for Metallic window screens.

One of the important objects of this invention is to provide a screenwhich is longitudinally and transversely adjustable and yet has therigidity of a single unit screen.

An object also is the provision of a screen of this class in which theadjustment for length and breadth may be easily and quickly made fromthe inner side of the screen.

A further object is toconceal the corners, after adjustment is made, bycorner pieces or rosettes at the outside of the screen.

An important object also is the provision of a screen of this class inwhich all of the side or frame elements are uniform in cross-section andmay be rolled into long lengths and cut to sizes to suit the particularscreen conditions.

Another important object of this invention is to provide a screen inwhich the screen or other element may be easily replaced, and installedby other than skilled mechanics.

Another object of this invention is the provision of .a screen of thisclass in which only the opposite short edges or ends of the screen, orsimilar element, are secured into place within opposite frame members,and the other or intermediate edges are free but positioned aconsiderable distance within the intermediate frame members.

With these and other objects in view, as will appear hereinafter, I havedevised an adjustable window screen having certain novel features ofconstruction, combination, and arrangement of parts and portions, aswill be hereinafter described in detail ,and particularly set forth inthe appended claims, reference being had to the accompanying drawingsand to the characters of reference thereon, which form a part of thisap- 'plication, in which:

Fig. 1 is an outside elevation of a window frame, showin my windowscreen, in its preferredform, placed thereover;

Fig. 2 is an elevation taken from the inside of the screen;

Fig. 3 is an enlarged fragmentary elevationtaken from the inside of onecorner and partly in section, omitting flange 4.

Fig. .4 is a similar View taken from the inside; Fig. 5 is an enlargedsectional elevation of the top frame member and of the screen adjustablysecured thereto, taken at 5-5 of Fig. 3; and,

Fig. 6 is another fragmentary sectional elevation taken at 6-6 of Fig.5, also showing the method of securing one edge of the screen to a framemember.

The frame for my screen, as shown in the drawings, is rectangular, andmade from metal tubing of substantially rectangular cross-sec tion. Thesides I- and upper and lower ends 2 are separate pieces, formed alike,and may be cut, with mitered ends, from a continuous length. Theseseparate pieces or frame members are secured together b angles 3, .aswill be described hereafter.

For convenience of description, the front walls or face portions of theframe members will be designated a, the outer sides or Walls b whichform the peripheral part of the frame, the inside walls 0, and innermostwalls d.

Although the general cross-section is rectangular, there is provided awide flange 4 which surrounds the frame, extending beyond the outer orperipheral walls I) of the frame consisting of said frame members. Theflange of each frame member is flush with the front wall or face a ofthe particular member. The flange consists of double metal plate and ismade by folding over the outer portions of the face a of the framemembers and the adjacent outer walls I) of the frame members. The flangethus formed locates the frame against the outer face of the windowframe.

The angles 3 consist of legs extending at right angles to each otherforming angle plates. The legs are inserted into the ends of adjacenttubular frame members and are positioned against the inner sides of theinside walls 0. The angles 3 are adjustably secured to the frame membersby screws l3 which are screwed into the angles and extend throughlongitudinal slots c near the ends of the inside walls 0 of the framemembers.

The screens are constructed to fit certain general sizes of windowframes, but are adjustable to fit variations of about one-half inch /2")of such sizes, due to inaccuracies, shrinkage, or the like. Enlargementof the screen frame will separate the mitered ends of the,frame membersand present an unfinished and unsightly appearance. To remedy thisdefect, I have provided corner pieces or rosettes 9 which are fastenedover the joints of the corners in any suitable manner such as bysnapping the same into place, or by screwing the same into place fromthe outside, as shown in Fig. 1.

The screen may be hung over the window frame in a conventional manner,which may consist of hooks 6 at the opposite sides of the top,

' ing hooks. 6.

of the window frame. At the upper ends of the flanges 4 of the sideframe members I and in the upper rosettes 9 are slots, designated 1 inFig. 4, of the drawings, for the reception of the support- On the insideof the bottom rail or frame member 2 is a suitable latch or hook 8 forsecuring the screen frame into place.

The removable or replaceable screen element consists of a wire meshorcloth 5 which normally has its edges inserted through a slot 01' locatedbetween flanges 3 extending inwardly from and intermediate the edges ofthe innermost Walls 11 of all of the frame members, as shown best inFig. 5. Only the top and bottom edges of the Wire cloth or screenelement 5 have rolled edges, beads, or enlargements e. These beads orenlargements are formed by rolling the edges around cords i2 and thenrolling tubular bars ll around the rolled'portions of the screen, orinserting the rolled edge portions of the screen within the splittubular bars.

The bar ll may have lateral extensions or yokes l5 for the reception ofthe shanks of adjusting screws H! which extend through the outside wallsb of the upper and lower, or transverse frame members 2. At least two ofsuch adjusting screws M are provided at each end of the screen element,that is, through the transverse frame members 2. As the adjusting screwsM are tightened the screen element 5 is drawn taut between the upper andlower frame members. This taut condition of the screen element preventsthe same from being withdrawn from the slots 11' of the side framemembers i.

In order to replace a screen, the adjusting screws It are removed fromthe end frame members 2, the rosettes e at the coincident ends of themembers i and 2 are removed, and also the adjusting screws l3'areremoved from such coincident ends. This permits the side frame member Ito be removed from such ends and also the rods I! to be withdrawn fromthe open ends of the end frame members 2. A new screen is substituted byinserting the rods H into the open ends of the top and bottom framemembers 2, securing the removedside frame members i back into position,replacing the rosettes, and inserting and drawing up the adjustingscrews M.

Though I have shown and described a particular construction, I do notwish to be limited to the same, but desire to include in the scope of myinvention the construction, combination, and

arrangement substantially as set forth in the appended claims.

I claim:

1. In a screen of the class described, a frame comprising tubular framemembers having slits at their inner sides, one of the frame members atone side of the frame being removable exposing open ends of adjacentframe members, a screen element having enlargements at opposite endsinsertable into said open ends of said frame members, said enlargementsbeing considerably larger than said slits, and means in one of thelatter frame members for tightening the screen.

2. In a screen of the class described, a frame comprising tubular framemembers, opposite frame members having slits at their inner sides, oneof the frame members at one side of the frame being removable exposingopen ends of adjacent frame members, a screen element having opposedroll edges at opposite sides, said roll edges being insertable into saidopen ends of the frame members and the adjacent portions of the screeninto the slits of the latter frame members, said roll edges being largerthan said slits, and means in one of the latter frame members fortightening the screen.

3. In a screen of the class described, a frame comprising opposedtubular frame members, two of said opposite frame members having slitsat their inner sides, one of the other frame members being removableexposing open ends of said two frame members, a screen element havingenlargements at opposite ends, said enlargements being insertable intosaid open ends of said frame members with the adjacent portions of thescreen insertable into the slits of the latter frame members, saidenlargements being larger than said slits, and means in one of thelatter frame members for tightening the screen.

4. In a screen of the class described, a frame comprising opposedtubular members having slits at their inner sides, said frame membersbeing open at one of their coincident ends, a screen element havingenlargements at opposite ends, said enlargements being insertable intosaid open ends of said frame members with the adjacent portions of thescreen into the slits thereof, said enlargements being larger than saidslits, and means in one of the latter frame members for tightening thescreen.
